without Elijah, they wouldn't have lived 1,000 years. Little did Rebekah know, Esther wanted to link them all then kill Finn so they all died along with the entire vampire race
As much as I love them they did Finn so wrong... Like he spent 900 years in a coffin , the love of his life forever separated from him so even if he hated it they never actually let him grow out of the self hatred
Elijah and Kol to me were the smartest outta the originals in terms of general knowledge like if you wanted to know something about the supernatural Kol would know and if you wanted to know anything else Elijah was your guy
